What is the relationship between the table of the eucharist and the table of teaching?

In his ninety-fifth homily on the reception of the holy mysteries, St. Jacob of Sarug links the eucharistic table with the teaching table. He says, “Come, you discerning, let us delight today in the teaching, the taste whereof is sweeter than honey and the honeycomb. Come and be filled with the table that is full of life, for its foods are unblemished for those who deserve them.”
